DIAL MECHANISM.

Application filed Il'anuaryfl?y 1,921. Serial N10. 'fiojt Torall ,whome't'mg/ concern Be it known that I, RICHARD LTR WIL- cox, a citizen of the United States, residing at Waterbury in the' county of New2 Hayn and State of OIluIlecticut, have invented certain new and useful' I'mprovements in. Dial: Mechanisms, of whichthe following is`4 a specification, reference being had thereinftoI the accompanying d'rawings.

My invention Arelates to new and useful improvements in dial mechanisms referring more particularly to meansV for transferring a blank from one station to another. and holding;= it at this latter station for one orl more Operations to be performed thereon.

It is the object of this invention, among. other things, to provide means whereby these desirable results may be accompl'ished with mechanism much more simple than has 'heretofore been used, more durablefin its Character, provided with means for adjustingthe yielding 'devices whereby the mechanism may. be unusually, sensitive but still eifective in its operation, and this yielding mecha-` nism so constructed and Controlled as to minimize the .possibility of its becomingdisarranged or broken and with these and many other ways to produce a superior device .of the charaoter described, withparts of simple construction, economical to construct, readily assembled and that willl operate automatically with little or no personal attention.

ATo these and other ends my. invention consists in the dial mechanism having, certain details of. construction and4 combinationsiof parts as will"be hereinafter described .and more particularly pointed out in the claims.

Referr-ing' to the drawings in which like numerals of reference designate like parts in the several figures:

Figure 1 is aA plan view of my vimproved mechanism as applied to a screw .slotting machine; Figure 2 .is an elevation thereof partly in section; and

Figure 3 is a side elevation of a portion thereof showing the means for actuating 'the gripping member. 4

My invention .as shown herein is analogous to the type of dia-l mechanism shown in Batent No. 1',029,653, issued tonie for improvements in slotting machines June 18,l '1912, and is for substantially the same purpose. The machine shown in said patent'isespe- Cially designed fon Slottng the heade Of screw blanks, but my inyentionv maybe used in` Connection with any Other type Of machine, if; desiretd. I have, therefore, only shown. such portion Of. the associated mechansm 'asm'ay be e-.Ssental for a- Clear-under.- standing of my improvements.

Referring particularly to. the drawings, the reference numeral designates the table ofl the machine with which my mechanism is paltticularly associated, and 11 the feed chute by which blanks are conveyed in a well known manner from a hopper, orl other source ofl supply to the dial mechanism, this chiiteV being preferably supported at one end by the brackets 12,. The numeral 13 designates a carrier dial that is provided with a plurality of peripheral notches 14 and secured' by a nut 15- or other similar means upon the shaf-t 16 that is journaled in the boss o r lug 17 connected with the table/10.`

`Mou'nted'so as to swing upon a fixed stud 18 is ,a rock lever 19 having mounted at one end a gripping member 20.- This gripping member is Vpreferably cylindrical 'in' form and is secured t'o the rock lever 19 by a screw. 21 or similar means.

By manipulation of this screw, the gripping member '20' may be rotated thereon' and held in any desired position by tightening the screw so as to prevent movement thereof. If desired, a boss `l22 may be provided upon the underside of: the gripping member that will`project into a corresponding recess in the rock'lever 19 so as to distribute the gripping strain between the lever and screw. This, however, is not ntirely essential'for other means may be'used to accomplish the same result. 1

A movement is imparted to the rock lever `19 in timed relation with the operation of other parts from a shaft 23,V a cam"24 mounted thereon, a rockllever 25 pivotally mounted upon a stud 26`h connected 'with the table 10 or other fixed' part'having an arm 27 thereon that proj ects upwardly and terminates in front of a filug 28 upon the end of the rock lever 19. `A set screw 29 is threaded through this lug, has a jamb nut `30 thereon, and its inner end contac'ts with the upper end of the ai'm 27, (see Figure').

Rotation of the cam 24 imparts a movement to .the lever 19 through the rock lever 25 so that the gripping member 20 is caused to move toward and away from the carrierI dial 13, the away movement being resistefl by a yielding mechanism comprising a plunger 31 supported in a casing 32 with its outer end held in contact with the rock lever 19 by means of a spring 33, the tension of which is varied by the set screw Zet through the end of the casing and engaging the button 35 in contact with the spring, a jamb nut 36 upon the screw 34 looking the screw against accidental movement in any of its adjusted positions;

I 'have 'shown herein guide plates 37 and 38 commonly'used with mechanism of this Character, although forming no part of my invention, as well as a stripper plate 39 and a stop plate 40.

The blanks, assumed foi` illustration to be headed blanks, which are to be slotted, pass downwardly through the chute 11 and the lowermost blanks enter one of the notches ltin the carrier dial 13 which then receives intermittent rotation, the blank being held against displacement by the guide plates 37 until it is brought into the position designated by the blank 41 in cross section,` at whichtime the rock lever 19 is moved so as to bring the gripping member 20 against one side of the blank and hold the same rigidly between the gripping dial and the gripping member, while a saw (not shown) is cutting a slot in the head thereof."` Upon completion of` the sa-wing operation, the cam again actuates the rock level' 19 and moves the gripping member 20 away from the carrierdial l'13, against the resistance of the spring 33. The carrier dial 13 again receives an intermittent rotation and carrying` with it the slotted blank that is held against displacement by the guide plate 38 and presenting a new blankat the sawing station, at which time the gripping member 20 is moved against the 'new'blank and the sawing Operations are repeated as before. c

"Heretofore'it has been the practice to so associate the means for holding the blank that the one is positively driven from the othenthat is, both having a positive intermit-tent movement. This necessitates' considerable mechanism such as gears, shafts, etc., a rotary gripping member that is either provided with lu'gs or recesses upon its outer surface and for these and in many other ways have objeotions that have mitigated against the use of this type of machine foi` certain classes of work.

.In the mechanism herein shown the gripping member` and carrier dial are entirely separate 'and distinct and acquire independent movement, the former is not rotated in this operation and the gri'pping pressure is onlyzapplied to the blank at the time when actually required and is notmaintained constantly as heretofore. The gripping. member may be used indefinitely and the possihility of injury thereto is reduced to the absolute minimum, there are no peripheral lugs or recesses to reo'ister with corresponding parts upon a carrier dial and liable to be broken or destroyed by reason of nonregistering therewith.

In these and many other ways my device herein shown is much more desirable for certain classes of work, much more simple in its construction, more positive and certain in its operation and is much less complicated and requires less skill in its construction and assembling.

While I have shown a cylindrical gripping member, Wherein by rotation, new faces may be presented to compensate for' the wear, if any, upon that portion subject to pressure, it is obvio'us that a grpping member, fiat in form and either rigidly or adjustably mounted uponvthe rooklever 19, may be substituted, if desired.

Minor changes and alterations may' be made within my invention, aside from those herein suggested, and Iwould therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.

What I claim is new and desire to secure by lLetters Patent, is: i i
